HYDROGARBON-PREHEATER FOR CARBURETERS.

Specification of Letters Patent.

Patented May 2'73, rare.

Application filed February 23, 1918. Serial No, 218,883.

To all whom it may concern Be it known that I, GEORGE E. Ross, a citizenof the United States of America, and a resident of Waterloo, Blackhawkcounty, Iowa, have invented certain new and useful Improvements inHydrocarbon-Preheaters for Carbureters, of which the following is aspecification.

My invention relates to improvements in hydrocarbon pre-heaters forcarbureters for internal combustion engines, and the object of myimprovement is to supply simple and inexpensive means for this purpose,adapted to be detachably mounted upon an exhaust pipe or other source ofheat adjacent to a carburetor, and be heated to conduct heat to anincluded conduit for the heavier kinds of hydrocarbons to change same toa vaporous condition and transmit same in heated condition to thecarbureter.

This object I have accomplished by the means which are hereinafterdescribed and claimed,.and which are illustrated in the accompanyingdrawings, in which Figure 1 is a perspective view of my improved deviceas mounted upon part of an exhaust-pipe of an engine; Fig. 2 is a sideelevation of the body parts of the device as slightly separated fromeach other, and Fig. 3 is a transverse section of these parts takenthrough one of thepin-sockets of the lower section.

In the drawings, similar numerals of reference denote correspondingparts through.- out the several views.

My hydrocarbon pre-heating device is of simple construction, consistingessentially of two body-parts 1 and 2 fitted together detachably, andpreferably formed of castiron. The lower part 1 has its lowerfacemedially longitudinally hollowed or downwardly troughed at 16semi-circularly to fit upon the exhaust-pipe 10 of an internalcombustionengine, or other pipe or body containing heating-means or being in aheated condition. The fiat top of the part 1 has an upper part orsection 2 superposed upon it in registration, the part 2 havingdepending pins 7 removably seated in sockets 6 in the part 1 to keep theparts in registration; The parts 2 and l have respectively registeringhalf parts of longitudinal medial hollows or'troughs 3 and 4, whichtaken together provide. a longitudinal cylindrical tubular openingthrough the assembled device to receive and hold a tubular conduit 9,separably.

When these parts are assembled as shown in Fig. 1, they are clampedtogether by the following means: The top of the part 2 has a medialtransverse flattened groove 8. The numeral 11 denotes a fiat metal bandwhich is clamped around said parts 1 and 2 me dially, the end parts ofthe band being seated in the transverse flattened groove 8 to preventrelative longitudinal movements, and the extremities of the band 12 and13 being bent upwardly and placed in registration and orificed in lineto receive a fastening bolt 14 secured adjustably by a nut 15. Thisclampingmeans as also the pins and sockets 7 and 6, keep the parts 1 and2 together in registration, to hold the tubes"9 and 10 in their seats.

The tube 9 is placed in communication between a carbureter and a supplyof any of the heavier hydrocarbons, such as kerosene or petroleum, andsince the highly heated gases which pass through the pipe 10 from thecombustion-chamber of an internal-com-- the simplicity of constructionof the de-.

vice, renders it useful in practice. The clamping-connections shown canbe adjusted easily, and'the part 1 may be blocked up to space it adistance from the pipe 10, when desired to vary the heat conducted tothe pipe 9.

-Having described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

'1. In a device of the character described,

a body made up of overlaid parts, one part being longitudinally troughedto embrace detachably the exhaust-pipe of an internalcombustion engine,said parts having registe-ring grooves forming an orificed channel toreceive a conduit for a liquid to be seated by conduction through saidparts, and clamping-means embracing said parts and said exhaust-pipe tohold them together detachably, said parts having mating engagrug-meansengaging to keep them in registration when fitted about saidliquid-conveying conduit.

2' In a hydrocarbon preheater in combination with the exhaust-pipe of anengine; a two-part body having registering plane surfaces provided Withregistering longitudinal troughs, a conduit-pipe for hydrocarbon seatedremovably in said troughs in contact With the body-parts, one of thebody-parts being troughed longitudinally along its under face to fitremovably over said exhaust-pipe, one of the body-parts having socketsin its said plane surface and the other body-part having pins in itsplane surface fitting said sockets removably, a flexible band passedabout said exhaust-pipe and body-parts, the upper body-part having atransverse groove to receive the band, and means for securing the endsof said band together detachably.

Signed at Waterloo, Iowa, this 12th day of Feb. 1918.
